PIANO-STOOL.

Specification of Letters Patent.

7 Patented June 8', 1915.

Application filed Qctober 14, 1912'. Serial No. 725,605.

" To all whom may concern:

Be it known that I, BYRON 0. Jones, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Piano-Stools, of whichthe following is aspecification.

This invention relates to pianostools and has for its object to providea newand improved device of this description.

My invention has among other-objects to provide a seating-device suchfor example as a piano stool which can be adjusted for use in playingthe ordinary piano and in playing a piano player. WVhen playing theordinary piano, the stool seat ortop should be fiat. When playing thepiano player, the operator is required to operate the bellows with hisfeet and it is very important that the seat be so arranged as tofacilitate this. By making the seat or top inclined so that the portionnearer the piano is higher than the other portion, the operator isgiven" a purchase on the seat so that he can easily and eflicientlyoperate the bellows of the piano player.

The invention is illustrated in the accompanying drawings, whereinFigure 1 is a view showing one form of stool embodying the invention;Fig. 2 is an enlarged view showing the connection between the stool seatand base; Fig. 3 is a sectional view taken on line 33 of Fig. 2; Fig. 4is a sectional view taken on line 4.4 of Fig. 8.

Like numerals refer to like parts throughout the several figures.

For purpose of illustration, I have shown my invention as applied to apiano stool hav ing a circular top. As herein illustrated, the top 1 ofthe stool is rotatably connected with the base 2 so that it can-beeasily turned,

and is preferably arranged so that it can be' raised and lowered byturning in the ordinary way. Means is provided for easily and quicklyinclining this top and holding it in this inclined position whendesired. In the construction shown, the top 1 is provided with aprojection 3. This projection is pivotally connected with a support.This support has two projecting parts 4 and 5, connected with thesupporting piece 6, which in turn is connected with the base 2. Theprojection 3 passes between the two projecting parts 4 and 5 and ispivotally connected with the parts 4 and 5 in some suitable manner as bymeans of a pin 7. The projection 3'is provided with an eccentric hole oropening 7*. Located within this opening is an eccentric 8 connected witha rotatable piece 9 mounted in the parts 4 and 5. The piece 9 isprovidedwith a handle 10 so that it-can be given a partial rotation.When the parts are in position as shown in Fig. 2, the top of the stoolis fiat, the stool being in proper condition to be used in playing thepiano. When it is desired to operate the piano player, the operatortakes hold of the handle 10 and 'moves it to the position shown indotted lines in Fig.1. This causes the eccentric 8 to be rotated in theenlarged open ing 7*, thereby causing the projection 3 to be moved tothe positionshown in Fig. 4. When in this position, the top 1 isinclined as shown in dotted lines in Fig. 1 so that the device is inposition to use the piano player. The high edge of-the top 1 is placedtoward the piano player thus giving the user a purchase on the seat sothat such user can operate the bellows easily and efliciently. The

top 1 is locked in this inclined or tilted position by means of the camas the pressure of the projection 3 on the cam is applied thereto sothat the cam can notbe rotated by this pressure. I prefer to arrange theaxis of rotation of the cam and the part 9 so that it will be'on oneside of the center of the pin 7. When it is desired to use the deviceinplaying the ordinary piano, the handle 10 is moved back to the positionshown in full lines in Fig. 1 which moves the top back to the flat orlevel position, the top being held rigidly in this position by the cam.The opening 7 is elongated longitudinally. It

is of'such width that the cam engages the sides thereof in all thevarious positions of the cam so that there will be no lost motion, andso that the full effect of the cam will be utilized in tilting the top.

I claim:

1. A piano stool comprising a top and a base, a single central standardconnecting the top and base, a movable connection in said centralstandard between the top and the base whereby the top may be moved to aninclined position, and means contained in said central standard forlocking the top in said inclined position.

2. A seating device comprising a top, a base'therefor, a centralconnection between the top and base comprising over-lapping parts on thetop and base, a piece passing through said overlapping parts by means ofconnected with said second piece and acting as an actuating device tomove said top when the second piece is rotated and as a lock to holdsaid top in any of its Various positions. A i

3. A seating device comprising a top and a base, a pivotal connectionbetween said top and said base, a rotatable part mounted upon said base,an eccentric forming a part of said rotatable part and engaging the partconnected with said top, said eccentric adapted when rotated to move thetop in an inclined position. 1

4. A seating device comprising a top, a projection connected therewithnear the middle thereof, a supporting piece for said top, a pivotalconnection between said projecti-on and said supporting piece, arotatable part mounted upon said supporting piece, an eccentricconnectedwith said rotatab'le palrt engaging said projection on the top,said eccentric adapted when rotated to move the top to an inclinedposition.

5. A seating device comprising a top, a.

supporting projection connected therewith, a supporting piece for saidtop, a pivotal connection between said supporting projection' and saidsupporting piece, a rotatable part mounted upon said supporting'piece, acam connected with said rotatable part engaging said supportingprojectionon the top, a handle connected with said rotatable part andadapted when moved to oneposition to move the top to an inclinedposition, and when moved to another position to move said top to itsfiat position.

6. A seating device comprising a top, a

supporting projection connected therewith, .a supporting piece for saidtop,- a pivotal connection between said supporting pro htable partmounted upon said supporting piece, a cam connected with said rotatablepart engaging said supporting projection on thetop, said cam adaptedwhen rotated to movethe top to an inclined position, the cam and pivotalconnection substantially in vertical alinernent, the axis of rotation ofsaid cam being located at one side of the 7 axis of rotation of the topabout its pivotal connection with the support.- Y

V, 7. A piano stool comprising a top and a base, a central connectionbetween the top and the base comprising over-lapping proje'cting partson the top and base, two connections between said over-lapping parts,

one a pivotalconnection and the other a V cam connection.

8. A piano stool comprising a top and a f base, a central connectionbetween thetop and the base comprising over-lapping projecting parts onthe top and base, a pivotal connection between said over-lapping parts,a rotatable part passing through said proi jections, said rotatable parthaving'a cam which engages one of said projections,

whereby when the cam is rotated the-inclination of the top will bevaried;

9. A piano stoolcomprising a top and a base, a central connectionbetween the top and the base comprising over-lapping projecting parts onthe top and base, a pin pass-' ing through said projections, a secondpin also passing through saidprojections, said second pin having threeparts of different diameters, one of said parts being cam shaped. r

In testimony whereof, I afliX my signature in the presence of twowitnesses this 11th day of October, 1912.
